"Problems to be Solved by the Invention" However, in such a conventional vehicle sunroof device, the connecting member 8 that connects and separates the drive base 4 and the brake base 7 is located in a position that is visible from inside the vehicle interior, so the appearance is poor. Not only is this bad, but since it is visible, it is possible to reach out and touch it, and the drive base 4 and brake base 7 may be unexpectedly disconnected, causing the sunroof to open and close abnormally. The dot was hot.

The present invention has been made in view of these conventional problems, and it is an object of the present invention to provide a sunroof device for a vehicle that solves the above problems by providing a good appearance and preventing tampering.

"Means for Solving the Problems" The gist of the present invention for achieving the above object is to provide an opening/closing body that can open and close a roof opening provided on a vehicle by either tilting or sliding, and a base base that pivots the base end portion of the opening/closing body;
a drive base that is vertically driven and has a follower pin that fits into an inclined cam groove formed rearward from the base end of the side part of the opening and closing body; and a drive base that is driven vertically; The opening/closing body is connected to the opening/closing body by slidingly fitting a braking base arranged on the side of the opening/closing body and connected via a connecting rod to a rail provided at the side edge of the roof opening. A connecting member that performs seesaw movement is attached to the brake base, and the connecting member includes a brake engaging portion that engages and disengages from a notch cut in the rail, and a brake engaging portion that engages and disengages from the drive base. and a connecting engagement portion at opposing ends, and when the drive base is on the base base side, the braking engagement portion engages with the rail and stops the opening/closing body in a non-slidable manner. The opening/closing body is tilted to open and close by the movement of the drive base, and when the drive base approaches the brake base, it is pushed by a part of the drive base and the brake engaging portion comes off the rail and closes the brake base. while releasing the brake, the connecting engagement part connects to the drive base,
In a vehicle sunroof device in which the opening/closing body can be slidably opened and closed, the connecting member is partitioned from the interior of the vehicle,
a horizontal wall that covers the top of the connecting member; a vertical wall that is folded from the inner end of the horizontal wall and covers the side of the connecting member; and a vertical wall that is folded from the lower end of the vertical wall and that slides into contact with the lower surface of the rail. The sunroof device for a vehicle is characterized in that a cover member having a fitting piece is fixed to the brake base by fixing the horizontal wall to the brake base from above.

``Function'' As a result of covering the connecting member provided on the brake base with the cover member, the connecting member does not come into contact with the eyes of people inside the vehicle, improving the external appearance and making it easier to touch. This is to prevent mischief etc. from occurring.

The cover member is fixed to the brake base and moves together with the movement of the movable base. Since the cover member does not move relative to the brake base, the cover member covers the connecting member compactly by the horizontal wall and the vertical wall so that the connecting member is accommodated therein.

When the brake base moves, the fitting piece of the cover member moves while slidingly contacting the lower surface of the rail, thereby preventing the lower end of the vertical piece from wobbling.
